Abstract

The invention discloses a porous ceramic heating element used for an electronic cigarette and a preparation method of the porous ceramic heating element. Electrodes are welded on the two ends of a porous ceramic matrix to obtain the porous ceramic heating element used for the electronic cigarette. The porous ceramic matrix is mainly prepared by preparing silicon carbide, alumina, silicon dioxide,molybdenum disilicide, magnesium oxide and a pore-forming agent in a certain proportion, then forming, sintering and other processes. The electrodes are formed by a metallized layer process. The porous ceramic heating element has a simple process and a stable structure and has no need for burying heating wires. The porous ceramic heating element can generate heat by itself, is uniform in heating and high in thermal conductivity, tobacco tar adsorbed in gaps can be heated evenly, and thus the heating uniformity, the heating efficiency and the taste of the electronic cigarette are all effectively improved.

Description

technical field [0001] The invention relates to the field of ceramic heating elements, in particular to a porous ceramic heating element for electronic cigarettes. Background technique [0002] The working principle of the porous ceramic heating element for e-liquid is mainly to use porous ceramics to absorb e-liquid to the heating wire, and the heating wire heats up to evaporate the e-liquid, thereby producing nicotine and other substances. Since the design of the prior art is that the heating wire is designed on the outside of the porous ceramic, there is a temperature difference between the inside and the outside of the porous ceramic, which affects the uniformity of heating and the taste of the electronic cigarette. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a porous ceramic heating element for electronic cigarettes and a preparation method thereof, which does not need to embed heating wires. The p...
